DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention in which the above objects can be specifically realized are described with reference to the accompanying drawings. In describing the present embodiment, the same name and the same reference numerals are used for the same configuration and additional description thereof will be omitted below.

In the present invention, since the outdoor unit of the ceiling type air conditioner has the same structure as the general outdoor unit of the separate type air conditioner, a detailed description thereof will be omitted. Hereinafter, the indoor unit structure of the ceiling type air conditioner will be described with reference to the accompanying drawings. If outlined as follows.

1 is a side cross-sectional view showing the indoor unit of the ceiling air conditioner according to the present invention, Figure 2 is a bottom cross-sectional view showing the indoor unit of the ceiling air conditioner according to the present invention.

The indoor unit of the ceiling-type air conditioner is mounted on the ceiling or embedded as a whole, the case 10 is installed on one side of the case 10, a blowing fan 20 for forced suction and discharge of indoor air and the case Installed on the other side of the inside of the 10 consists of a heat exchanger (30) for cooling the indoor air sucked by the blowing fan (20). In addition, the indoor unit of the ceiling-type air conditioner is installed at the lower end of the heat exchanger 30 and the drain pan (40) having a box shape having an upper surface open to collect the condensate generated during the heat exchange process Include.

First, the case 10 has a box shape (ie, a cassette), and basically protects components such as an internal blower fan 20 or a heat exchanger 30. In addition, the case includes a discharge port 11 and a suction port 12 communicated with the room, respectively. Here, the suction port 12 is installed on the bottom surface of the case 10 adjacent to the blowing fan 20. On the other hand, the discharge port 11 may be installed near the lower edge of the case 10 because the indoor unit itself is mounted to the ceiling surface as shown in the present invention. Therefore, due to the formation of the discharge port 11, the air heat-exchanged after being sucked is discharged directly without changing the flow path, thereby substantially improving the discharge efficiency of the air conditioner.

In addition, a control unit (not shown) is attached to the outside of the case 10, and a controller and related parts for controlling the operation of the blower 20 and the heat exchanger 30 according to an external input therein. Is located.

The blower fan 20 is a cross-flow fan in the present invention, and the cross-flow fan sucks and discharges air in a plane perpendicular to the axis of the fan instead of the suction flow in the axial direction. . A crossflow fan having such characteristics is generally advantageous for air conditioners, particularly ceiling type air conditioners such as the present invention, because it can produce a fixed pressure large airflow and evenly flow in the axial direction.                     

More specifically, the crossflow blower fan 20 is rotatable entirely, as shown in FIG. 2, in which some components such as the heat exchanger 20 are omitted for detailed illustration of the blower fan 20. Directly connected to the motor 24 provided on one side by the drive shaft. In addition, the blowing fan 20 is composed of a plurality of unit fans 21 connected in series via an annular boundary plate 21a. Each unit fan 21 includes a pair of boundary plates 21a and a plurality of blades 21b arranged in the circumferential direction thereof between the boundary plates 21a. In addition, the blower fan 20 includes a rear guide 22 and a stabilizer 23 having a structure for guiding the discharged air due to the characteristics of the crossflow fan. In this case, the rear guide 22 and the stabilizer 23 are each formed of a plate-shaped member installed on the outer shell of the blowing fan 20, as shown in FIG.

On the other hand, the cross-flow blower 20 is classified into a suction type installed adjacent to the suction side of the mounted device or a discharge type installed adjacent to the discharge side according to a method of flowing air. Can be. In the present invention, the discharge type cross flow blow fan 20 is applied to be suitable for direct air discharge to the discharge port 11 described above, and the suction port 12 is formed adjacent to the blow fan 20 as shown. According to the structure of the blower fan 20, the rear guide 22 is curved in accordance with a predetermined curvature to guide the air discharged into the indoor unit and extends to the vicinity of the heat exchanger 30. In addition, the stabilizer 23 forms a flow path extending to the heat exchanger 30 for stabilizing vortices occurring in the inner and peripheral regions of the blower fan 20 and for being discharged together with the rear guide 22. do.                     

The heat exchanger 30 is an evaporator which is connected to a compressor and a condenser and a refrigerant pipe provided in an outdoor unit to form a refrigeration cycle. Basically, the low temperature and low pressure liquid refrigerant passing through the refrigerant pipe passes through heat between the heat exchange fins. It takes away and vaporizes, cooling the indoor air. In addition, the heat exchanger 30 is preferably inclined toward the discharge port 11 side as shown in Figure 1 in order to increase the heat transfer area. In this case, when the heat exchanger 30 is excessively inclined, the inclination angle of the heat exchanger 30 may be appropriately set since condensate may fall from the heat exchanger 30 to the outside of the drain pan 40 by its own weight. It is desirable to be.

Finally, the drain pan 40 includes a drain pipe (not shown) connected to one side and communicating with the outside in order to discharge the condensed water continuously generated during operation. In addition, although not shown in the drain pipe is connected to the drain pump for forcibly discharging the condensed water in the drain pan 40 to the outside.

On the other hand, the indoor unit of the ceiling-type air conditioner described above is difficult to be installed to be embedded in the ceiling due to the discharge port 11 formed in the lower edge of the case 10. That is, the cooling air is not properly supplied to the room due to the air flow direction from the discharge port 11 during the ceiling embedded installation. To this end, as shown in FIG. 3, in another embodiment of the present invention, a discharge guide 50 having a predetermined shape is mounted at a lower edge of the case 10 in which the discharge hole 11 is formed. In more detail, as shown in FIG. 4, the discharge guide 50 is installed at the lower edge of the case 10 and is vertically and horizontally connected to the vertical and horizontal members 51a and 51b connected to each other. Side members 52a and 52b attached to both side surfaces of the members 51a and 51b, and auxiliary discharge holes 53 formed in the horizontal member 51b. In addition, the discharge guide 50 preferably further includes a protruding member 54 formed at the ends of the vertical and horizontal members 51a and 51b to be easily mounted. When the ejection guide 50 is mounted, the protruding member 54 is formed to serve as a seat of a fixing member such as a screw or has an adhesive property so that the ejection guide 50 is itself without the other fixing member. ) Can be attached.

The discharge guide 50 may be detachably mounted to the lower edge portion and guides the air discharge from the discharge port 11 downward. Therefore, the indoor unit of the ceiling type air conditioner of the present invention together with the discharge guide 50 may be installed to be embedded in the ceiling.

Referring to the operation of the ceiling-type air conditioner according to the present invention having such a configuration as follows.

First, when the blowing fan 20 is rotated by the motor 24, a vortex is generated inside the blowing fan 20, the forced flow of air is generated by this vortex. More specifically, the low pressure region is formed on the suction side of the blowing fan 20 and the high pressure region is formed on the discharge side during rotation. That is, the air is sucked into the blower fan 20 through the low pressure region, and becomes a vortex that rotates and is discharged through the high pressure region while being guided by the rear guide 22 and the stabilizer 23. As such, the indoor air forcedly sucked through the inlet 12 formed on the bottom surface of the case 10 by the action of the blowing fan 20 flows a predetermined distance inside the indoor unit, and then passes through the heat exchanger 30. It is cooled while being cooled after being finally put into a predetermined indoor space through the discharge port (11).

Here, when the indoor unit is mounted to the ceiling as shown in Figure 1, since the discharge port 11 is formed in the lower corner of the case, the cooled air passing through the heat exchanger 30 is directly indoors without changing the path Can be discharged.

In addition, when the indoor unit is embedded in the ceiling as shown in FIG. 3, the cooling air discharged by the ejector 11 is first guided by the vertical member 51a of the discharge guide 50. Thereafter, the cooling air can be stably supplied to the room even when the cooling air is discharged through the auxiliary discharge port 53 formed in the horizontal member 51b.

Although several embodiments have been described above, it will be apparent to those skilled in the art that the present invention may be embodied in many other forms without departing from the spirit and scope thereof. Accordingly, the described embodiments are to be considered as illustrative and not restrictive, and all embodiments within the scope of the appended claims and their equivalents are included within the scope of the present invention.
